Abstract

The effects of electron injection were investigated in Mn-doped GaN. Electron injection introduced noticeable changes in the minority carrier diffusion length and cathodoluminescence. Recombination of nonequilibrium electron-hole pairs created by scanning electron microscopy (SEM) technique was found to cause the band-to-band cathodoluminescence. A multi-fold decrease of the band-to-band cathodoluminescence intensity in the temperature range of -50°C-80 °C. The results of the temperature-dependent cathodoluminescence measurements reveal a possible recovery of the cathodoluminescence intensity with an activation energy of 360 meV.
